On the solution of (n+1)-dimensional fractional M-Burgers equation
Alexandria Engineering Journal, 2021 In the paper, (n+1)-dimensional fractional M-Burgers equation with a force term in the sense of the Caputo fractional derivative is considered. We solve this equation using homotopy perturbation method (HPM) and find its approximate analytical solution ...

Relative effects of breastfeeding intention and practice on maternal responsiveness
Infant Mental Health Journal: Infancy and Early Childhood, Volume 41, Issue 1, Page 82-93, January/February 2020., 2020 ABSTRACT Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother–infant dyads from a U.K.‐based birth cohort study the Avon Longitudinal Study of Parents and ...

A Hypothetical‐Mathematical Model of Acute Myeloid Leukaemia Pathogenesis
Computational and Mathematical Methods in Medicine, Volume 11, Issue 1, Page 49-65, 2010., 2010 Acute myeloid leukaemia is defined by the expansion of a mutated haematopoietic stem cell clone, with the inhibition of surrounding normal clones. Haematopoiesis can be seen as an evolutionary tree, starting with one cell that undergoes several divisions during the expansion phase, afterwards losing functional cells during the aging‐related contraction

Mathematical Model Creation for Cancer Chemo‐Immunotherapy
Computational and Mathematical Methods in Medicine, Volume 10, Issue 3, Page 165-184, 2009., 2009 One of the most challenging tasks in constructing a mathematical model of cancer treatment is the calculation of biological parameters from empirical data. This task becomes increasingly difficult if a model involves several cell populations and treatment modalities.

On the Nagumo uniqueness theorem
, 2011 By a convenient reparametrisation of the integral curves of a nonlinear ordinary differential equation (ODE), we are able to improve the conclusions of the recent contribution [A. Constantin, Proc. Japan Acad. {\bf 86(A)} (2010), 41--44]. In this way, we
